How to get all the assets in a Collection in AEM?

I am trying to get all the assets inside a collection in AEM given the path of the collection.

Let's say the path of the collection is /content/dam/collections/public/-/-XZMzZlhkJKIa7-Mg15h/testing

I need to get all the assets inside this collection.

I checked under content/dam/collections the assets are not stored under this location

I even tried by writing a query in query builder in AEM giving type:dam:asset and path:"location of the collection"

I couldn't get any results.

I just need to get all the assets under the collection in Java or QueryBuilder

Storing assets in the collections would be a bad idea since assets can be part of multiple collections. Like in a playlist the assets are only referenced in the collection.

Every collection has a subnode "sling:members". This subnode has a (multi value) property sling:resources that holds references to each asset that is member of this collection. On top of that, sling:members also has subnodes of type nt:unstructured for each asset with a property sling:resource and again the path to the asset.

enter image description here

So you can either iterate the property values or the subnodes to get references to the assets and then access them at their original location.

Resource Collection API will be used to retrieve the assets in a Collection.

Below code should work for you.

Resource resource = resourceResolver
            .getResource("/content/dam/collections/k/kXjI0j44sW4pq2mWc9fE/public collections");
    if (null != resource) {
        log.debug("resource path is {}", resource.getPath());
        ResourceCollection resourceCollection = resource.adaptTo(ResourceCollection.class);
        if (null != resourceCollection) {
            Iterator<Resource> resourceIterator = resourceCollection.getResources();
            while (resourceIterator.hasNext()) {
                Resource damResource = resourceIterator.next();
                log.debug("damResource path is {}", damResource.getPath());
                imagePaths.add(damResource.getPath());
            }
        }
    }
